Okay, let’s tackle this. So Yvonne has 3 years of experience as an interior designer. Location is Flint, Michigan, which is a mid-sized city. According to the Bureau of Labor Statistics, interior designers in the Midwest typically earn lower median salaries compared to those on the East or West Coasts. However, considering her experience and location, I'll estimate a lower rate. Typically, junior interior designers in the US can earn around $40–$60 per hour. Given Yvonne's experience, maybe around $45 per hour, which is slightly above the lower end of the range.
